Atwood Machine

The figure shows two blocks connected by a cord (of negligible mass) that passes over a frictionless pulley (also of negligible mass). The arrangement is known as Atwood's machine. Block 1 has mass m1 = 1.70 kg; block 2 has mass m2 = 2.50 kg. What is the tension in the cord? Assume a y axis has its positive direction upward.
